Chromodoris strigata, commonly known as the streaked chromodoris, is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
Chromodoris strigata is pale blue with black longitudinal lines on its body and upper mantle. It has a bright orange-edged mantle and bright orange gills and rhinophores. This species is easily confused with Chromodoris elisabethina but has a distinctive darker area in the middle of the back.
This species, like many other nudibranchs, feeds on sponges. It has been seen feeding on yellow sponges from the family Darwinellidae.
